The ad view reads everything on the ad account, including campaigns made in Ads Manager years ago and campaigns someone else created, not only ones linked to posts from Cybe Social. Amounts are in the ad account's currency, and figures from two ad accounts are never added together.
The default window is all time. To match a number someone is reading in Ads Manager, pick the same date range; a mismatched window is the usual reason two numbers disagree.
Cybe Social holds read access only. It cannot create, edit, pause or fund a campaign. For cross-channel reporting that joins Meta Ads with Google Ads, GA4 and your CRM, we build marketing intelligence dashboards as a separate service.
